Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission from a wet wipe with blood on it coming into contact with the urethra.
From the information given, this scenario is determined to be of No Risk (HIV transmission is not possible in the given scenario). This scenario is determined to be of No Risk because it does not fulfill the requirements of our HIV Transmission Equation (see image below). In order for HIV transmission to occur, HIV positive fluid (blood, semen, vaginal fluid, anal fluid, breastmilk) must have direct access to the bloodstream through a high, low, or sometimes negligible risk activity.
Although you mention the presence of blood, the requirement of "direct access to the bloodstream" is not satisfied in this scenario. Additionally, the blood you have described on the wet wipe has been exposed to oxygen before coming into contact with the urethra, rendering HIV transmission nearly impossible. HIV in fluid that is exposed to the environment such as on the surface of a wet wipe is quickly rendered inactive, making transmission difficult to achieve (1) (2).
Recommendation: No need for HIV testing with the scenario provided, refer to a healthcare professional for other health related questions.
